MOWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 455,482, dated July 7, 1891.

9 Application filed October 29, 1890. Serial No. 369,746- (No model.)

To all whom it may concern:

Be it known that I, ROBERT H. DIXON, a citizen of the United States, residing at Still- Water, in the county of Washington and State of Minnesota, have invented certain new and useful Improvements in Mowing-Machines, of which the following is a specification.

My invention relates to that class of mowers having two carrying-wheels, both of which are preferably drivers and having a fingerbar jointedto its supporting member and adapted to be tilted by the driver, and is designed as an improvement upon my mower patented under date of September 23, 1890; and the objects of my invention are, first, to provide a support for the knife-operating gearing which shall rock with the finger-bar; second, to provide bearingsfor the knife-operating gearing in a single piece which shall rock with the finger-bar; third, to connect the knife with its operating crank-wheel by a pitman which shall rock with the finger-bar, and in general to improve the construction and operation of the mower. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 isa plan View of my mechanism. Fig. 2 is a section of Fig. l on line 2 2, showingthe driving-gearing and clutch.

Similar letters of reference refer to the same parts throughout the several views.

The frame A is pivotally supported upon the axle B of the wheels B B in the usual manner, and this part of the mechanism may be varied to suit the requirement of construction or wishes of the builder. The rocking coupling-piece A has its stubbleward end pivoted to the frame A at A In the construction here shown this pivoted connection is.made with a socket in the frame covered by a cap A and a ball on the coupling-piece held in said socket; but any other form of construction may be used which will give a free vertical and rocking movement to the inner end of the coupling-piece to which the finger-bar is attached. The finger-bar C, a part only of which is shown, is jointed to the rocking coupling-piece A by the shoe 0 at a and a. A wheel D may be pivoted on the front end of the shoe 0 to assist in carrying the finger-bar when desired. The push-bar E connects the rocking coupling-piece A and which connection, whether by a equivalent connection which should be axially frame A by pivoted joints, permitting the free movement of the rocking coupling-piece while giving it due support for its work. The lifting-lever F connects the frame A with the rocking coupling piece A in the usual manner and does not need a detailed description here. The rocking lever G, attached to frame A'and connecting an arm 0 of the rocking 6o coupling-piece A.- by the rod G, is of well- -known constructionand need not be further described. 7 The wheels B B may be ratcheted to the shaft or axle B in the usual manner. The sprocket-wheel K is fastened upon shaft 6 5. B. The sprocket-wheel K is fastened to the stubbleward end of shaft L, which has its) bearings in the coupling-piece A, upon which shaft is the bevel-gear L and clutch L cone structed and operating in the usual manner. 76 Motion is given to the driving mechanism by the chain K upon sprocket-wheels K and K. The bevel-gearL meshes into pinion M, which is fastened on the rear end of shaft M, supported transversely in bearings in couplingpieceA.

On the front end of shaft M is the crankwheel M on which is the wrist-pin m. The pitman N connects the knife 0 at its head 0,

stud extend- 8o ing outward from the knife or a hole in said head in which a right-angled turn of the pit r man may enter, should be parallel axially with the wrist-pin on the crank-wheel, and the pitman may be a single piece, either made of wood or metal, and its connecting ends provided with holes to attach wrist-pins, or an parallel, which construction of the pitman, in

connection with the rocking coupling-piece, o

will permit all needed movements of the finger-bar. It should be noted that the socket A in frame A is formed upon an arm A extending stubbleward from said frame between the sprocket-wheels K and K, and that the sprocket K is close to said socket, and is therefore not materially affected by the vertical movement of the finger-bar end of said coupling-piece.

Various changes can be made in the construction here shown without departing from the scope of my invention, and I do not wish to confine myself to the exact construction here shown,

WhatI claim as my invention, and desire to secure by Letters Patent, is-

1. In a moWing-1nachine,the combination of the frameA and a rocking coupling-piece pivoted to said frame substantially in line With the finger-bar and stubbleward of the driving mechanism, said coupling-piece adapted to provide bearings for theknife-driving gearing and to rock with the finger-bar, operating substantially as and for the purpose set forth.

2. The combination of the frame A, the rocking coupling-piece A, pivoted to said frame substantially in line with the fingerbar and stubblewardof the driving mechanism, and a finger-bar pivoted to said rocking coupling-piece with means for operating the same, substantially as specified.

3. The combination of the frame A, the rocking coupling-piece A, with the knife-operatin g gearing seated thereon, and an arm projecting stubbleward from said frame to provide apivoted bearing for the stubbleward end of the rocking coupling-piece substantially in line with the finger-bar, operating substantially as and for the purpose set forth.

4. The combination of the frame A, the rocking coupling-piece A with the knife-operating gearing seated thereon, the sprocket- Wheels K and K, and an arm extending stubbleward from said frame A between said sprocket-wheels to pro vide a bearing for the end of the said rocking coupling-piece, substantially as set forth. 5. The combination of frame A, the rocking coupling-piece A, With the knife-operating gearing seated thereon and, provided with a pivoted ball at its stubbleward end and pivoted substantially in line with the fingerbar, and the arm A provided with the socket A operating substantially as and for the purpose specified.
